Have you ever taken a shower, put on clean clothes, used deodorant and somehow still noticed an unpleasant smell later in the day?
Or maybe you’ve wondered why some people sweat a lot without smelling, while others seem to develop body odour much more easily.
Well, here’s something you might not know: Sweat itself doesn’t actually smell.
So, where does body odour come from? Let’s talk about it.
What Is Body Odour?
Body odour, also known as bromhidrosis, is an unpleasant smell that develops when sweat interacts with bacteria on the skin.
Sweat itself is mostly made up of water and is generally odourless. The smell develops when bacteria on your skin break down substances in your sweat, producing compounds that create the unpleasant smell we associate with body odour.
So yes, you can sweat a lot and still not have strong body odour. It’s the interaction between sweat and bacteria that creates the smell.
Why Does It Happen?
A few things can make body odour more noticeable:
- Hormones: During puberty, hormonal changes make the apocrine glands around areas like the armpits and groin more active. The sweat from these glands contains substances that bacteria can break down, which can produce a stronger smell.
- Exercise: Physical activity increases sweating and the more sweat sitting on your skin, the more opportunity bacteria have to interact with it.
- Hot weather: If you live somewhere hot and humid, you already know the struggle. Heat makes you sweat more, while humidity can make it harder for sweat to evaporate.
- Stress and anxiety: Ever noticed sweaty palms before an interview or presentation? Stress can increase sweating and sweat from the apocrine glands may contribute to stronger body odour.
- Genetics: Your genes can influence the composition of your sweat and how it interacts with bacteria, which is one reason everyone’s natural body scent is different.
- Health Conditions: Conditions such as hyperhidrosis, diabetes and some hormonal, kidney or liver conditions can sometimes affect sweating or body odour.
How Can You Manage Body Odour?
The good news? There are simple ways to reduce body odour.
-
Bathe regularly: Washing helps remove sweat, bacteria, oils, and dead skin cells that can contribute to odour.
-
Use deodorant or antiperspirant: Deodorants help control odour, while antiperspirants reduce sweating.
-
Wear breathable clothing: Light, breathable fabrics can help reduce moisture trapped against your skin.
-
Change sweaty clothes: Especially after exercise or spending a long time outside.
-
Pay attention to your diet: Foods such as garlic and onions can sometimes affect body odour. If you notice a particular food consistently changes your scent, it may be worth paying attention to.
When Should You See a Doctor?
Sometimes, body odour is simply a normal part of being human, but if you suddenly develop a strong or unusual smell that doesn’t improve with regular hygiene, or if you experience excessive sweating that interferes with your daily life, it’s worth speaking with a healthcare professional. Especially if the change comes with other unusual symptoms.
A Gentle Reminder: Body odour is normal,everyone sweats and everyone has a natural body scent. Managing body odour isn’t about trying to smell like perfume all day, it’s about keeping yourself clean, comfortable and confident while paying attention to changes in your body. And please, don’t shame someone simply because they have body odour. Sometimes, it isn’t as simple as just taking a bath, because our hormones, genetics, environment, lifestyle and health can all play a role. Take care of your body. Be kind to yourself, because good hygiene isn’t about being perfect, it’s about being healthy, comfortable and confident in your own skin.
